Rewrite Equations
x=10; y=−5x+30
Step: Solve x=10
for x: x=10
Step: Substitute
10 for x in y=−5x+30:
y=−5x+30
y=(−5)(10)+30
y=−20
(Simplify both sides of the equation)
Answer: x=10 y=-20 (10,-20)

The rectangular prism has a surface area of square inches.
254 square inches
Step-by-step explanation:
In order for us to easily answer this problem, let us make the units uniform. So 1 kiloliter is equivalent to 10 hectoliters. This would mean that 11 kiloliters is 110 hectoliters. Since 40 hectoliters is for making ice cream, only 70 hectoliters of milk is left to be used in other ways. Hope this answers your question. Have a great day!
Answer:
x = 70
y = 40
Step-by-step explanation:
First, we need to find the measure of x.
As x and the angle 110 share a line, they must add up to 180 degrees. This means that the measure of x is 70.
The two ticks on the sides of the triangle indicate that these sides are equal in length. This also means that the corresponding angles will also be equal. This means that both x and the other angle are 70.
This means that we have two of the three angles in the triangle, so we can easily find the third, which is y.
